To all "whom it may concern Be it known that I, JAMES H. DooLnY, a. citizen of the United States, and resident of East Orange, in the county of Essex and I State of New Jersey, have invented certain new and useful Improvements in Speed Regulators and Indicators for Phonographs, of which the following is a specification.

The object of the present invention is to provide an improved form of speed control for .)honographs and similar devices that will be very simple and economical both in its construction and operation, and at the same time will be accurate and etlicient in its results.

In the accompanying drawings showing one embodiment of my invention, Figure 1 is a side elevation of the device as applied to a phonograph mechanism. Fig. 2 is a plan view of the same parts. Fig. 3 is a side elevation of the actuating means for the control. Fig. 1 is an end elevation of the same. Fig. 5 is a view from the opposite side of that shown in Fig. 3. Fig. 6 is a section on the line 6-6 of Fig. 5. Fig. 7 is a plan view partly in section of the same parts; and Figs. 8 and 9 show the supporting frame for the indicating disk.

As shown in the drawings 1 represents the supporting board of the instrument, and 2 a frame in which is mounted the governor, comprising a shaft 3 having a collar at fast thereon. A series of weights 5 are connected by spring 6 between said collar 4 and a collar 7 slidab-le on the shaft 3. To the collar 7 is fast a disk 8 that on rotation of the shaft 3 will move along the shaft by the outward swing of the weights 5. It is customary in this art to provide an arm to engage this disk 8 when on elevation of the speed it is desired to retard the rotation of the shaft 3. I show an arm 9 pivoted at 10 to swing toward and from the disk 8 and which has a buffer 11 that engages the disk. The arm 9 is provided with an extension 12 whereby its position can be varied.

To swing the arm 12 I provide a suitable drum 13 rotatably mounted and which is swung by a suitable head 14: having a gear 15 thereon that engages the drum to turn the same. In one face of the drum I arrange a spiral slot 16 into which the end portion of the extension 12 projects. On turning the head, the drum will rotate, and the arm 12 will have its free end move vertically up or down and this will swing the arm 9 to shift the buffer to and from the disk 8 of the governor. Obviously this change of position of the bufier will cause it to be engaged by the disk at a higher or lower speed of the governor and thereby regulate the maximum speed at which the instrument will operate.

As shown the drum is in the form of a hollow shell having twoq face plates and a periphery or sleeve. One of these face plates and the sleeve may be integral in the form of a cup and the other disk is rigidly connccted to the top of the cup. As shown, the disk 17 has the sleeve or periphery 18 integral therewith, which disk has a circular series of apertures 19, adapted to engage the teeth of the gear 15 fast on the head 14. The spiral slot 16 is cut in the disk 20 that is socured to the cup shaped member.

I provide a supporting plate 21 in which the head 14 is rotably mounted with the head above the plate, and the gear 15 below the same. This supporting plate is secured at an opening 22 in the board 1 of the instrument. The hollow drum l3. is,shown as supported by a frame comprising a slotted arm 22 on one side having a curved extension 23, that connects with a similar curved extension 24 parallel thereto on the opposite side, these curved port-ions being connected by base portions 26 and 27, that are secured to the supporting plate 21 on each side of the head 14. These parallel plates 23 and 24 support the spindle 28 on which the drum 13 rotates, in position for engagement with the gear 15. The extension 22 contains a vertical slot 30 that is radial of the drum and adjacent the spiral slot 16. It will be seen from Figs. 2 and 6 that the arm extension 12 projects through the slot 30 into the spiral slot 16. On turning the head 14, the portion of the spiral slot registering with the radial slot, will advance to and from the axis of the drum and the arm will thus be swung in the radial slot. will shift the buffer to and from the fric tion disk 8 of the governor. It is evident that the spiral slot will act as a cam, and the drum will remain in any position to which turned by the head.

It will thus be seen that most of. the parts are die-stamps or die-cuts and practically no machine work is required on the parts. Thus This movement the device very economical to construct and at the same time very etlicient in operation.

Having thus described my invention, What I claim is 1. In a speed control, the combination with a speed governor including a rotary disk axially movable on change of speed, of a brake arm movable toward and from the disk, an extension on said arm, a rotary drum having numbers thereon, an apertured plate adjacent the drum, a rotary head, a gear on the head engaging said drum to turn the drum and cause the numbers to appear successively at the apertured plate, one face on the drum having a spiral slot engaging said extension \vhereby to swing the brake arm on turning of the drum by the head.

In a speed control the combination with a speed governor including a rotary dish axially movable on change of speed, of a brake arm movable toward and from the disk, an extension on said arm, a rotary drum having numbers thereon, the drum having a spiral slot in one face, an apertured plate adjacent the drum, a rotary head turning in said plate, a gear on the head meshing with the drum to turn the drum and bring its indications to appear successively at the apert-ured plate, a support for the drum comprising a base having parallel arms, aspindle supporting the drum to turn between said arms, one of said arms having a slot extending radially of the drum and adjacent the said spiral grooved taco ot' the drum, said arm extension projecting through said slotted arm into the spiral groove whereby turning oi the ,drum by the head will svving the extension and arm.

In a speed control the comiination with a speed governor including rotary disk axially movable on change of speed, of a brake arm movable tovvard and from the disk, an extension on said arm, a rotary nollow drum having indications on its periphery, the drum hav' ig a spiral slot in one face and a circular series oi holes on the opposite lace, an apertured plate adjacent the periphery of the drum, a rotary head turning in said plate, a gear on the head meshing with the apertured face the drum to turn the drum and bring its indications to appear successively at the apcrturcd plate, said arm extension projecting into the spiral groove, whereby turning of the drum by the head will swing the extension and arm.

l. in a speed control the combination with a speed governor including a rotary disk axially movable on change of speed, of a brake arm movable toward and from the disk, an extension on said arm, a rotary drum having indications on its periphery, the drum having a spiral slot in one face and a circular series of holes on the opposite ta'ce, an apertured plate adjacent the periphery of the drum, a rotary head turn-- ing in said plate, a gear on the head meshing with the apertured face of the drum to turn the drum and bring its indications to appear successively at the apertured plate, a support for the drum comprising a base having parallel arms, a spindle supporting the drum to turn between said arms, one of said arms having a slot extending radially oi the drum and adjacent the said spiral grooved face of the drum, said arm extension projecting through said slotted arm into the spiral groove, vvhereby turning of the drum by the head will swing tne extension ano arm.

In a speed control the combination with a speed governor including a bralrc arm, an extension on said arm, a rotary drum having indications on its periphery, the drum having a spiral slot in one taco, an apertured plate adjacent the drum, a rotary head turning in said plate, a gear on the head meshing with the drum to turn the drum and bring its indications to appear successively at the apertured plate, a support for the drum comprising a base having parallel arms, each arm being bifurcated at the base and connected by two bars secured to the said plate on opposite SltlOSOif the said head, a spindle supporting the drum to turn between said arms, one of said arms having a slot extending radially of the drum and adjacent the said spiral face of the drum, said arm extension projecting through said slotted arm into the spiral groove, whereby turning of the drum by the head will swing the extension and arm.
